The presented result is a knowledge contribution to the biological diversity and characterization in Nipe - Sagua-Baracoa Massif, which contains the greater endemic natural resources of the country.

Many and different scientific innovations have been presented, including news reports of plants and animals for Cuba and the massif, the study of the anthropic effect of vegetal formations on diversity, study about bryophytes distribution in different vegetal formations and contributions to their conservation and endemism state, a complement of pteridological flora with data about its conservation state, dynamics of species loss by anthropization, new Cuban reports and new possible taxons for Science, the compilation of the massif’s phanerogamic flora diversity by phytogeografic districts, with new data on its conservation state that solidly prove the imperious need of conservative and management measures. There are also included as novelties new syntaxons, described for pine rain forests, evergreen and semideciduous forests, as well as the functional characterization of two ecosystems belonging to rain forests of low attitude and mesophyllic evergreen forests.

The massif's ethnoflora was characterized, providing recommendations for its sustainable use and its perspectives for medicinal use.

There are presented similar new results in the case of the massif's Fauna, contributing significantly to know more about insects. We consider that the realization of biodiversity studies and the application of numeric indexes to characterize it according to the anthropic action are novel for Cuba.

Arachnids, mollusks, amphibians, fishes, reptiles and birds are listed, and there are studied their endemism, conservation state, habits, numeric indexes that characterize the biodiversity, distribution modeling for birds, etc.

The results are presented in 2 volumes and 1 CD with images and synthetic information on the most outstanding flora and fauna, which constitutes an important instrument for university and postgraduate teaching.
